The NSW government is overfunding well-off private schools by hundreds of millions of dollars while underfunding the state's public schools by billions per year, according to a new report.

The NSW Teachers Federation-commissioned report estimates the state government will overfund private schools by around $850 million in the five-year period from 2019 to 2023.
